The Load of Pleasure

Description

Evelyn, impatient with her friend's delay, jokingly asks if she's coming to her house on a mare. To her surprise, her friend does show up, but on the back of her new sex slave, who, despite being slow, assures her that she can carry the two girls. The friends decide to test the slave's determination by giving orders to be carried on her back. While the slave makes sounds of exhaustion that resemble moans of pleasure, the friends become increasingly aroused by the situation.
